CNC Machined Iron Casting Turbine Components for the Power Generation Industry

01. Challenge

When a power generation customer needed a gas turbine inner barrel, they relied on Aeromet’s skill and expertise to handle the machining of this critical, high-quality CNC component.

02. Approach

The customer supplied the iron casting and Aeromet’s engineering staff used CAD/CAM software to design the barrel and create a solid model. The inner barrel was CNC machined on our Giddings and Lewis vertical turning lathe and with our Stanko horizontal boring mill. This component had a turned finish, a diameter of 60”, a height of 40” tall, weighed 2,100 lbs. and met tolerances of ±.002”.

03. Results

Components were examined during the machining process, and at completion, the barrel was extensively inspected to meet ISO 9001:2015 standards. Aeromet assembled, packaged, and delivered the parts to the customer's facility.
